Urgent Freelance AWS Security Specialist – Key Invalidation & Forensic Investigation

We are seeking an immediate, short-term Freelance AWS Cloud Security Administrator to respond to a credential exposure incident. Two AWS access keys have been leaked, and we require an expert to jump in immediately to perform two critical tasks: securely disable/revoke the compromised credentials and conduct a thorough forensic investigation to find the exact source and cause of the leak.
You will be responsible for tracking the lifecycle of the leaked keys, auditing global account activity via AWS CloudTrail to ensure no rogue resources or backdoor accounts were created, and verifying the integrity of a specific EC2 instance. This is a task for a professional who can deliver rapid containment and clear root-cause analysis.
